Natural gas prices in metro Atlanta are among the lowest they've been all year.

Georgia Natural Gas Providers release their rates in units called therms once a month. For September, Infinite Energy comes in the lowest at .49 per therm. Add in distribution fees and the average bill is $34.07 a month, $711 for the year according the Georgia Public Service Commission.

To decide whether to lock in a rate, take a look at your bills and see what rate you're paying. Also review your current contract to see if there are any charges for switching providers. Right now fixed rates are lower than variable rates in many cases.
